ALSTOM PIB201A Feeder Protection Relay

Advanced Power Protection Systems

Main Features and Benefits

The ALSTOM PIB201A offers robust and reliable protection for medium-voltage distribution networks through its microprocessor-based design. Engineered for critical power applications, it combines three-phase overcurrent protection with sensitive earth fault detection in a compact, cost-effective package. The relay’s adaptive protection algorithms continuously monitor network conditions to optimize tripping characteristics for different operating scenarios.

Key operational advantages include:

• Advanced thermal modeling: Motor protection algorithms calculate real-time thermal capacity based on measured current
• Configurable logic: User-programmable function blocks enable custom protection schemes without firmware updates
• Disturbance recording: Integrated event recorder captures 128 time-tagged events with oscillographic capability

The PIB201A features a large backlit LCD display with multiple language support for clear operational status visualization. Front-accessible communication ports enable on-site configuration without cabinet access, while the non-volatile memory preserves settings during power interruptions. Compliant with IEC 60255 standards, this relay withstands severe electromagnetic environments common in industrial electrical substations.
